Overview

This experiment is to verify practically the calculated voltage values for the given circuit and verifying it using cut-set method. A cut set of a graph is a set of branches whose removal, cuts the connected graph into two parts such that the replacement of any branch of the cut-set renders the two parts connected. To find a cut-set, first select a tree, then a tree branch, and divide the graph into two sets of nodes by drawing a dotted line through the selected tree branch and appropriate cotree links while avoiding intersection with any other tree branches. From the cut-sets a cut-set schedule is made with tree branch as the row and all branch numbers as the column. This matrix is referred as Qf. The voltage branches can be calculated by solving this matrix calculation, VB = QfTVT.
1. Connect the circuit as shown.
2. The voltmeters are connected across all the branches to measure the branch voltages.
3. Run DC analysis without sweep and you will get the DC voltages as measured by the voltmeters.
